The Correct Option is D

Solution and Explanation


Step 1:
Assume capitals according to the given ratio. Let \[ A=5x,\qquad B=3x \] Both invest for 12 months. \[ A=5x\times12=60x \] \[ B=3x\times12=36x \]

Step 2:
Calculate C's capital-time product. C joins after 6 months and invests equal to A. \[ C=5x \] Investment duration: \[ 6 \text{ months} \] Thus, \[ 5x\times6=30x \]

Step 3:
Find profit ratio. \[ 60x:36x:30x \] \[ =10:6:5 \] Hence, \[ \boxed{10:6:5} \]
